We own a 12-seater van. It's done us good service for 10 years. But we've been paying huge money towards maintenance and repairs. One mechanical problem after another. The mechanic seems to be not doing his job well. We recently fired our mechanic. We decided that he's incompetent for failing to use his mechanical abilities and training. But solely relied on our van's computer system. So, we found another one, John, who has proven his work to be credible. He uses his greased bare skilled hands, keen eyes in seeing what's wrong with our van. John has no understanding with computerized mechanisms of our van. So, he would not understand what the computer would say, anyway. Maybe, the programming is outdated. But John's skills are practiced and up to date; and his customer service trustworthy. I love the good old traditional fix-it mechanic!
